Computers, TVs, Lighting and Glasses
Will working at a computer screen hurt my eyes?
No, there is no evidence that working at a computer damages the eyes. However, long hours of work can be fatiguing to the eyes, neck and back. Monitor glare from various light sources can also be a problem. It is often helpful to take periodic breaks, looking off in the distance and adjusting your work station (angle of the monitor, height of the chair, changing the lighting, etc.).
Will sitting too close to the television set hurt my child’s eyes?
No, there is no scientific evidence that TV sets emit rays that are harmful to the eyes.
Why have I gradually found it harder to read without glasses?
The ability to focus on near objects decreases steadily with age and is referred to as presbyopia. Presbyopia is a natural aging of the lens. It is usually near the age of 40, when glasses or bifocals are prescribed to correct this condition.
Are sunglasses good for my eyes?
There is a benefit to wearing UV protective lenses–wearing them may protect against cataract formation. Clear lenses with UV protection may offer greater protection than dark lenses because they allow the eyes to be exposed to more light. This causes greater constriction of the pupil which lets less light enter the eyes.
Is my child likely to inherit my need for glasses?
Possibly. If both the biological parents wear glasses, your children are likely to need them as well.
Will reading in dim light hurt my eyes?
No, but most people are more comfortable reading with proper lighting which is bright enough to provide good illumination but not so bright as to cause glare.
How often do I need to get my prescription changed?
There is no predetermined schedule for changing glasses or contacts. It is necessary to change your prescription only when it no longer provide adequate correction. However, it is still a good idea to have regular eye examinations.
What materials are available for glasses?
Some of the newest materials for frames include titanium (virtually indestructible) and polycarbonate materials (recommended for high impact sports). Lenses are also made from polycarbonate materials, other types of light weight plastics and glass. Coatings include UV protection (recommended for all types of lenses), scratch-resistant protection, polarization, anti-glare and others. See the Kellogg Optical Shop for more information about glasses.
